+# Docker images used for gRPC testing
+
+Most of our linux tests on the CI run under a docker container, since that makes it easier
+to maintain the test environment and the dependencies. Having an easily reproducible test
+environment also make it easier to reproduce issues we see on CI locally.
+
+The docker image definitions we use live under `tools/dockerfile` directory (with the
+exception of `third_party/rake-compiler-dock` docker images).
+
+## Version management
+
+The docker images we use for testing evolve over time (and newer/older versions of it
+might not work with newer/older revisions of our code).
+
+For each dockerfile (which is identified by the directory in which is it located),
+the "current version" that's being used by testing is determined by the
+corresponding `.current_version` file, which contains the full docker image name,
+including artifact registry location, docker image name, the current tag and the
+SHA256 image digest.
+
+Example:
+For `tools/dockerfile/test/cxx_debian11_x64/Dockerfile`, there is a
+`tools/dockerfile/test/cxx_debian11_x64.current_version` file which contains info
+as follows:
+```
+us-docker.pkg.dev/grpc-testing/testing-images-public/cxx_debian11_x64:[CURRENT_CHECKSUM]@sha256:[CURRENT_SHA256_DIGEST]
+```
+This info can be passed directly to `docker run` command to get an environment
+that's identical what what we use when testing on CI.
+
+## Updating the images
+
+The authoritative version of docker images we use for testing is stored in artifact registry,
+under the repository `us-docker.pkg.dev/grpc-testing/testing-images-public`.
+
+If you've made modifications to a dockerfile, you can upload the new version of the artifact
+registry as follows:
+
+Rebuild the docker images that have been modified locally and upload the docker images to
+artifact registry (note that this won't overwrite the "old" versions of the docker image
+that are already in artifact registry)
+```
+tools/dockerfile/push_testing_images.sh
+```
+
+Build modified docker images locally and don't push to artifact registry. This option is
+very useful for quick local experiments. The script is much faster if it doesn't have to
+interact with artifact registry:
+```
+# very useful for local experiments
+LOCAL_ONLY_MODE=true tools/dockerfile/push_testing_images.sh
+```
+
+## Migrating from dockerhub
+
+In the past, our testing docker images were [hosted on dockerhub](https://hub.docker.com/u/grpctesting),
+but we are in the process of migrating them artifact registry now.
+
+This temporary feature might simplify the migration:
+```
+# try pull existing images from dockerhub instead of building the from scratch locally.
+TRANSFER_FROM_DOCKERHUB=true tools/dockerfile/push_testing_images.sh
+```
